STATEN ISLAND, N.Y. — A Stapleton man was so drunk when police pulled him over on the Staten Island Expressway early Saturday morning that he had to hold on to the side of his Ford Explorer for balance as he walked, police allege.

Police say Cesar Moreno-Garrido, 26, of Jackson Street, had a blood alcohol content of .243 percent — more than three times the .08 percent legal threshold for driving while intoxicated — after he was stopped for driving on the shoulder of the Expressway by Slosson Avenue about 2:45 a.m.

He’s charged with aggravated driving while intoxicated, which is triggered when a defendant’s blood alcohol level exceeds .18 percent, and driving while intoxicated. ---Follow @siadvance on Twitter
